If you can, save the pictures on the card to your computer. Use the camera to FORMAT the card. Now you should be able to shoot again. This happens when the camera is saving a pictures and runs out of battery power. It has happened to me several times.

Based on the information you've provided, it seems that the Lens Mechanism of the Camera is damaged when it fell down. The Lens of the Camera is not focusing properly while capturing the images. As the issue is with the lens mechanism, the previously captured images are displaying normally. I suggest that you try resetting the Camera and check if the issue can be resolved.

Performing a manual power reset

Turn off the camera.

Remove the battery pack.

Press and hold the power button for 30 seconds.

Allow the camera to remain without power for 60 seconds.

Reinsert the battery pack.

Turn on the camera.

To reset the Camera back to factory default, select the INITIALIZE Option from the SET UP1 Menu of the Camera to OK.This will set the user defined settings back to factory default. The images and videos will not get deleted.

A stuck shutter is another common failure mode for digital cameras, particularly for the SD1000. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open).
To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

By the way, my wife's SD1000 also has this problem every once in a while. I easily fix it by using the following steps from the link: powering on the camera, opening and closing the battery door, and
flicking the end of the lens barrel with my fingertip (or you can tap it with a pencil as discussed in the link).

This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check this link for more info.

to make the green square show up just press the shutter button until half (this is called the half press) when the green square shows up then it means that the camera has focused already, if not repeat the process til green square comes out you can press the shutter button fully to take picture when you see the green square...

I see this problem everyday : the CCD sensor is faulty ( see enclosed pic from a canon camera with similar specs ) this is why you can not capture normal undistorted images but have no problem with playback .Fortunately Casio will repair this free of charge so contact your agent.

If you're seeing black or distorted images both on the LCD and on the recorded pictures, then this might be a defective CCD imager.

Applicable cameras include:A40, A60, A70, A75, A80, A85, A95, A300, A310, S1 IS, S60, S200, S230, S330, S400, S410, S500, SD100, SD110

The filename (e.g. DSC0012.jpg) shows the image number, the filespec shows the date and time recorded. Most software will give you document info about resolution of the image. I wouldn't worry about what the battery status was when the shot was taken or how many other images were on the Mstick.
I guess I'm not sure what you need.
